He got a job in California at a milk company where he was the "Adohr Milk Company Whistling Birdman" and would go to schools praising the virtues of milk. One day he dropped off his business card at Walt Disney's studio. In his interview, he recited "Mary Had a Little Lamb" in the voice that would make him famous (one story has it that he was trying to do a baby goat) and when Disney heard it, he immediately knew he'd found the voice for his duck. Another story has Disney hearing Nash on a local radio show.
